[IRCA] Alberta TPs for 6 November 2018

2018-11-06 Thread Nigel Pimblett
No sign of any Asians returning here yet after the solar hiccup. Quite a number of weakish DU signals did make it today though. Australians heard on 549, 612, 774, 792, 828, 891, 1548 and good reception of KUAU from Hawaii on 1570, which had been missing during the good Asian conditions.

My initial impression of the band on Monday morning held up through closer inspection of my FDM-S2 recordings: it was dismal indeed. Although I'll take coastal DXing any day over inland, the "sea gain" effect still bows down to the propagation gods. Tuesday morning showed promise from around 1400

--- Begin Message --- I find it interesting that a very similar BOG / receiving antenna discussion is also going on with the Topband reflector. There's a fair amount of belief that terminated loops in a phased array or just a single double loop style (DHDL, DKAZ, Bowtie, Waller Flag) can deliver

IN its basic sense, the name "BOG" came from "Beveridge -on-Ground", and indeed one of adequate length should behave similarly. I don't know either of the two people you mentioned, but any of my interactions with 160 meter guys have resulted in some very strange ideas Russ Edmunds WB2B

Thanks Chuck; I knew I could bring you out of the woodwork. There's been a fair bit of hand-waving on the topband list about the BOG over the years, partly because anecdotally, either they "don't work", or that they have very good F/B. K2AV has done a lot of measurements, and seems to conclud

My experience is exclusively on a sand beach. We found early on that a normal ground wouldn't work. We ultimately ended up with a fan of 4 radials through, IIRC about 220 ohms. We haven't been able to use BOG's since Hurricane Sandy several years back. We had one running up the coast ( 37 degre

I don't see the self-terminating thing. It seems to me (unscientifically) that the losses are maybe 5 to 7 dB. That's a far cry from the 30 or more dB loss in a properly terminated system. Chuck From: IRCA on behalf of Nick Hall-Patch Sent: Tuesday, Novemb

Have you had success terminating a BOG Russ? (supposedly it is ~200 ohms, rather than the raised Beverage's ~450 ohms). I think some have found that it is self terminating, to a degree, as there is quite a bit of loss on reflected signals. best wishes, Nick At 20:07 2018-11-06, Russ Edmu

Didn't the discussion also cover whether the hum increases in intensity as Chongjin fades down, and decreases as it dominates the frequency? I believe that increasing hum with increasing Chongjin signal strength would indicate that the hum is part of Chongjin's signal, rather than due to the

Or could the hum be just heterodyne caused by 50 Hz difference between Chongjin tx and Heilongjiang? I checked via a Japanese receiver and I don't see strong side carriers, which would be typical for mains hum otherwise. Mauno Gary DeBock kirjoitti 6.11.2018 klo 9:25: A few months back ther

It isn't a dumb question because the answer is yes and no. If you terminate a BOG at one end, that should more focus the reception pattern in favor of the terminated end. If you're looking for stations from the N, then terminate at the N end. In the event that the desired result is an antenna wh

160 meters, being above the AM/MW band could be effective at somewhat shorter distances than for AM/MW, but 150-200' isn't really a BOG ( Beveridge on Ground ) it's a longwire. A BOG needs to be upwards of 500' I would think. I've used BOG's on MW/AM ranging anywhere from 500' to 1200'. The main di
